This data shows assumed
specifications for each WTC 1 core column at Floor 98 inferred
from information available; predicted maximum temperature at 102
minutes for various proportions of FRC removed; demand and
capacity; reduction in yield strength at maximum temperature; and
demand:capacity ratio (cold and maximum temperature). It should
be possible to print all the figures in landscape orientation;
there are 25 variables per line, comma separated. Alternatively,
adjust text size for best display of data. The CSV records may be
imported to a spreadsheet by stripping off the text and HTML
coding. See review of results and further discussion in Fires
Part Four.

Some variables are
self-explanatory. Here is a full list, with further details as
necessary.

Column number; yield
strength (ksi); cross-sectional area (ins^2); the nnn weight per
linear foot W14xnnn specification assumed for the column (lb/ft);
cold capacity of the selected member size (tons); cold capacity
based on the calculated demand and NIST published d/c ratios;
width W1 or d as viewed normal to the web and including the short
tf sides of the flanges (ins); width W2 or bf as viewed normal to
a flange; total heat absorbed after 102 minutes for totally
exposed member (MJ); final column temperature with FRC totally
stripped off on all four sides based on total absorption but
without taking into account flame or gas temperature limits (C);
final temp also under fully exposed conditions but imposing an
850C limit; final temp assuming one side or one-quarter of FRC
removed; final temp with FRC fully intact; axial gravity load at
floor 98 (tons); cold capacity of the selected member repeated as
before for comparison with demand; yield strength reduction
factor with all FRC removed; strength reduction factor with one
side or one-quarter of FRC removed; strength reduction factor
with all FRC intact; final column capacity after 102 minutes with
all FRC stripped off (tons); final capacity with three-quarters
of FRC remaining; final capacity with all FRC remaining;
pre-impact cold demand / capacity ratio; final d/c ratio with all
FRC removed; final d/c ratio with one-quarter of FRC removed;
final d/c ratio with all FRC intact.
